U.S. President Donald Trump will be off to the G-20 summit in Japan at the end of this week where he is scheduled to meet with China’s President Xi Jinping face-to-face for a high-stakes discussion on trade and other issues.

While most officials don’t expect a long-awaited breakthrough yet, Politico says it is possible that Trump could be talked into not putting new tariffs on even more Chinese imports. rump has continually preached patience during high-profile negotiations with China, North Korea, Iran, and other nations. It’s both for strategic reasons and as a way to smooth over any frustrations with the slow pace of progress. Trump may also believe that the U.S. can simply outlast its adversaries in trade disputes.

The pesticide industry is asking the Trump administration to exempt its chemical imports from China from the potential $300 billion in new 25 percent tariffs the president is threatening to impose next month on Chinese goods. CropLife America and a specialty chemical trade group filed comments with the U.S. Trade Representative’s Office. Those comments say the tariffs would hit a wide range of products that farmers rely on to do their jobs. Those products would include glyphosate, 2,4-D, atrazine, and dicamba. The groups say many of the chemicals that would be subject to the proposal are not available from American sources, and many others are not reasonably available from sources outside of China in the volumes needed and within a useful time period.
